Many are linemen, esp in college too. Many top linemen and linebackers are Samoan.
Out of all the linemen, in the NFL, epecially the top defenses, very few are Samoan.. Hell, i was watching the USC/UCLA game, and i saw very few Samoans, or in any of the AAC games (Duke is taking the national B-ball championships this yr!!). But if you needed big guys on the line, since Samoans have a propensity for big big, I can see why there will be more Samoans filling the ranks of the NFL and Div-! college.
If Samoans were great athletes, then they would rule the track and field, NFL, NBA,etc.
I went to school with some Samoans, and there are Samoans at my gym, I just see them as being big and fat.More so on the "big" part than fat, I guess you would call them stocky. The weight they are pushing up is more or less than any fat black, white, hispanic, paki, would push.
The Rock (Dwayne Johnson) got lipo because he could get that shredded look, because he's half Samoan.
And that "black vapire" bber (forgot his name), he has stated since he's half Samoan, it hard for him to get shredded.
